The present disclosure provides methods of treating subjects having hearing loss, methods of identifying subjects having an increased risk of developing hearing loss, and methods of detecting Kelch Domain Containing 7B (KLHDC7B) variant nucleic acid molecules and variant polypeptides.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of treating a subject having hearing loss with a therapeutic agent that treats or inhibits hearing loss, wherein the subject has been determined to have a Kelch Domain Containing 7B (KLHDC7B) missense variant nucleic acid molecule encoding KLHDC7B K181fs or KLHDC7B G302fs.
2. The method according to claim 1, wherein the KLHDC7B missense variant nucleic acid molecule is: lacking a guanine at a position corresponding to position 2,807 according to SEQ ID NO:1; or lacking a guanine at a position corresponding to position 3,170 according to SEQ ID NO:1; or an mRNA molecule having a nucleotide sequence: lacking a guanine at a position corresponding to position 673 according to SEQ ID NO:4, lacking a guanine at a position corresponding to position 673 according to SEQ ID NO:6, lacking a guanine at a position corresponding to position 1,036 according to SEQ ID NO:4, or lacking a guanine at a position corresponding to position 1,036 according to SEQ ID NO:6; or a cDNA molecule produced from an mRNA molecule, wherein the cDNA molecule has a nucleotide sequence: lacking a guanine at a position corresponding to position 673 according to SEQ ID NO: 12, lacking a guanine at a position corresponding to position 673 according to SEQ ID NO: 14, lacking a guanine at a position corresponding to position 1,036 according to SEQ ID NO: 12, or lacking a guanine at a position corresponding to position 1,036 according to SEQ ID NO: 14.
3. The method of claim 1, wherein the subject has conductive hearing loss.
4. The method of claim 1, wherein the subject has sensorineural hearing loss.
5. The method of claim 1, wherein the subject has neural hearing loss.
6. The method of claim 1, wherein the subject has been determined to have a KLHDC7B missense variant nucleic acid molecule encoding KLHDC7B K181fs.
7. The method of claim 1, wherein the subject is heterozygous for the KLHDC7B missense variant nucleic acid molecule encoding KLHDC7B K181fs.
8. The method of claim 1, wherein the subject has been determined to have a KLHDC7B missense variant nucleic acid molecule encoding KLHDC7B G302fs.
9. The method of claim 1, wherein the subject is heterozygous for the KLHDC7B missense variant nucleic acid molecule encoding KLHDC7B G302fs.
10. The method of claim 1, wherein the KLHDC7B missense variant nucleic acid molecule is a genomic nucleic acid molecule having a nucleotide sequence lacking a guanine at a position corresponding to position 2,807 according to SEQ ID NO:1.
11. The method of claim 1, wherein the KLHDC7B missense variant nucleic acid molecule is a genomic nucleic acid molecule having a nucleotide sequence lacking a guanine at a position corresponding to position 3,170 according to SEQ ID NO:1.
12. The method of claim 1, wherein the KLHDC7B missense variant nucleic acid molecule is an mRNA molecule having a nucleotide sequence lacking a guanine at a position corresponding to position 673 according to SEQ ID NO:4.
13. The method of claim 1, wherein the KLHDC7B missense variant nucleic acid molecule is an mRNA molecule having a nucleotide sequence lacking a guanine at a position corresponding to position 673 according to SEQ ID NO:6.
14. The method of claim 1, wherein the KLHDC7B missense variant nucleic acid molecule is an mRNA molecule having a nucleotide sequence lacking a guanine at a position corresponding to position 1,036 according to SEQ ID NO:4.
15. The method of claim 1, wherein the KLHDC7B missense variant nucleic acid molecule is an mRNA molecule having a nucleotide sequence lacking a guanine at a position corresponding to position 1,036 according to SEQ ID NO:6.
16. The method of claim 1, wherein the KLHDC7B missense variant nucleic acid molecule is a cDNA molecule produced from an mRNA molecule, wherein the cDNA molecule has a nucleotide sequence lacking a guanine at a position corresponding to position 673 according to SEQ ID NO:12.
17. The method of claim 1, wherein the KLHDC7B missense variant nucleic acid molecule is a cDNA molecule produced from an mRNA molecule, wherein the cDNA molecule has a nucleotide sequence lacking a guanine at a position corresponding to position 673 according to SEQ ID NO: 14.
18. The method of claim 1, wherein the KLHDC7B missense variant nucleic acid molecule is a cDNA molecule produced from an mRNA molecule, wherein the cDNA molecule has a nucleotide sequence lacking a guanine at a position corresponding to position 1,036 according to SEQ ID NO:12.
19. The method of claim 1, wherein the KLHDC7B missense variant nucleic acid molecule is a cDNA molecule produced from an mRNA molecule, wherein the cDNA molecule has a nucleotide sequence lacking a guanine at a position corresponding to position 1,036 according to SEQ ID NO: 14.
